TTP224 4-Channel Touch Sensor Module

The TTP224 is a 4-Channel Touch Sensor, meaning it has four touchpads. Whenever a capacitive load such as human hands is brought in proximity with the sense pad, the sensor then senses the change in capacitance and activates the switch. Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric or even wood. Each Touchpad has its respective output pin when the user touches a pad, the corresponding output pin will go high. It is very easy to interface with microcontrollers like Arduino to control different applications as a switch. It can be used in home automation, motor control, Relay control, etc. the module basically gets rid of the push button troubles.

You can also check our 16-Channel(TP229),  8-Channel(TP226), and Single Channel (TP223) Touch sensors if you are looking for other options. 

Specifications

Product Description

To connect it with Arduino, connect Pins VCC and GND to power up the module. Connect the Output pins to any Digital I/O pins of the Microcontroller Board. Whenever the user touches the pad the corresponding LED will light up and the pin will go High. You can read this signal by using the Digital Read command.
